TECHNICAL FIELD

[0001] The utility model relates to endoscope technical field especially is related to a adjustable endoscope. BACKGROUND

[0002] In the field of medical devices, the development of endoscopes is of great significance to improve surgical precision and efficiency. Traditional endoscopes have certain limitations in surgical applications. For example, the transoral cholangioscope commonly used in digestive surgery requires cooperation with a duodenoscope to reach the target surgical position via a guide wire. However, when consumable instruments such as biopsy forceps and baskets are needed, the guide wire must be removed first before inserting the consumable instruments. This operation method makes the surgical procedure complex, increases the operation time, and may cause additional risks to the patient.

[0003] For example, the patent with the authorization announcement number CN221129829U discloses an endoscope with an instrument channel and a guide wire channel set in the handle part. Consumable instruments enter the target position via the instrument channel, and the guide wire enters the target position via the guide wire channel. The instrument channel and the guide wire channel are independently set, which facilitates medical staff to simultaneously insert consumable instruments and guide wires and other objects. However, due to the fixed angle setting of the instrument channel and the guide wire channel, the insertion difficulty of the instruments and the guide wire is increased, and there is an urgent need for a structure that can adjust the insertion angle of the instruments or the guide wire.

DETAILED DESCRIPTION

[0022] The technical solutions of the utility model will be described clearly and completely in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

[0023] In order to realize the adjustment of the channel angle, so as to facilitate the insertion of the instrument or the guide wire, a kind of adjustable endoscope is designed, as shown in Figure 1 As shown, the endoscope includes handle part and insertion part, handle part is provided with instrument channel 2 and guide wire channel 3, consumable instrument enters target position via instrument channel 2, guide wire enters target position via guide wire channel 3, instrument channel 2 and guide wire channel 3 are independently arranged.This part of structure has been disclosed in detail in the patent with authorized announcement No.CN221129829U, and here is not described.

[0024] The core of the technical solutions is that, as shown in Figure 2 Handle part includes outer shell 1, two slots 11 are formed in outer shell 1, instrument channel 2 and guide wire channel 3 are arranged in slot 11 respectively through adjusting seat for adjusting angle.Specifically, adjusting seat includes support 4 installed in slot 11 and rotating bead 5 rotatingly arranged in support 4, instrument channel 2 and guide wire channel 3 are arranged on rotating bead 5.When consumable instrument and guide wire etc. are inserted, instrument channel 2 or guide wire channel 3 can be manually pushed to adjust the angle of channel, so as to facilitate the insertion of consumable instrument and guide wire etc.

[0025] The support 4 is provided with a plurality of side support plates 6 near one side of the inner part of the outer shell 1, which are evenly distributed in a circle with the center of the support 4 as the center, and are fixedly connected with the instrument channel 2 and the guide wire channel 3 through the first tension spring 61. The first tension spring 61 exerts tension on the channels, so that the channels can automatically return to the initial position under the action of the tension of the first tension spring 61.

[0026] The included angle between the central axis of the guide wire channel 3 at the initial time and the central axis of the insertion part at the initial time is 125°-145°, preferably 135°, and the included angle between the central axis of the instrument channel 2 at the initial time and the central axis of the guide wire channel 3 at the initial time is smaller.

[0027] As shown in Figure 3 and 4 , the support 4 is provided with a limiting upper cover 8 away from the inner part of the outer shell 1, a circular hole 81 is formed in the center of the limiting upper cover 8, which can extend out the rotating ball 5, and is used to limit the rotating ball 5 in the support 4. The inner diameter of the circular hole 81 is larger than the outer diameter of the instrument channel 2 and the guide wire channel 3, so that the channels can rotate in the circular hole 81, and the inner diameter of the circular hole 81 is smaller than the maximum outer diameter of the rotating ball 5, so that when the limiting upper cover 8 is screwed to abut against the rotating ball 5, the rotating ball 5 can be locked by the limiting upper cover 8.

[0028] In order to further expand the adjustment range, the support 4 is further provided with a sliding seat 9, which is slidingly arranged in the notch 11. The position of the channel can be adjusted by pushing the sliding seat 9, which further facilitates the adjustment of the position of the channel by medical staff. When the position of the channel changes, the angle between the channel and the hose and the insertion part will also change, thereby further facilitating the insertion of consumable instruments and guide wires and the like.

[0029] The sliding seat 9 is fixedly connected with the inner wall of the notch 11 through the second tension spring 91 at both ends, and the second tension spring 91 is correspondingly provided with two groups. When the sliding seat 9 moves, the second tension spring 91 will also act, so that the second tension spring 91 deforms and stores energy. When the force acting on the sliding seat 9 disappears, the sliding seat 9 can be reset by the second tension spring 91.

[0030] As shown in Figure 5 , in order to limit the position of the sliding seat 9, the side edge of the sliding seat 9 is provided with an extension section 7, which extends out of the notch 11 and is connected with a locking plate 71, and the locking plate 71 is provided with a locking screw 72 which can abut against the outer wall of the outer shell 1. By tightening the locking screw 72, the locking screw 72 abuts against the outer wall of the outer shell 1, so that the position of the sliding seat 9 can be locked.

[0031] The above description is only illustrative in nature and is not intended to limit the present application, and those skilled in the art can make many modifications, changes or equivalents without departing from the spirit and scope defined by the appended claims.
